PC
Most of these Deathstar drives failed young. This one, installed in Aug 2006, did not. Still running when it tripped the temp alarm at 13 years service. Not bad. And that motherboard has the Bad Capacitor plague! […]

Directional
What’s more fun than getting a call at sunset, informing you that the AM directional Antenna is out of limits and transmitter has also shut down? Nothing. Nothing at all. Let’s go see what fun awaits! At […]
Armstrong
Oh boy. This is an early Armstrong Solid state FM Transmitter. Closing in on 20 years service. These units were built by RVR in Italy and badged, (and fortunately still supported) by Armstrong. A 100W exciter feeds 5- […]
2200
Orban Optimod 2200. These are still nice sounding units and work just fine in many markets. They don’t breathe fire, but it’s tough to make one sound truly bad. When they do it’s often op amp. failure. This one had […]
FX50
BE FX50 If there were awards for best overall analog FM exciter, this one will win a ribbon. Broadcast Electronics FX-50. They still sound great even by today’s standards. We’ll start by stripping this one down […]
Another FX30
This one had all sorts of bad behaviors, including a rumble on-air. First stop is a new Fan. These Papst fans are pretty well built, but eventually the bearings wear. Main filter cap is also long past […]
Radix
Radix These are about the simplest, no-nonsense distribution amplifers on the market. Made exclusively for BSW I believe. A simple +/- 15V supply with two-three tab regulators and 34- NE5534’s. Yes, 34 of them. This one needed a -15V regulator. […]
Marti
Marti Electronics At one time you couldn’t step foot in a radio station without finding something “Marti”. In this instance it’s a STL-10 95oMhz Studio-Transmitter link transmitter. These units are getting up there in age, with the beige colored units […]
Nicom
Transmitters! These days you can put 10kW of FM on the bench to repair. Fun times. Nicom NT250. In this case the NT stood for “not transmitting”. Nicom packs almost everything but the PA on a single board. […]
Valley Audio
Valley Audio 401 Mike processors. Long out of production but they still get the job done. Mountain Dew. It’s always Mountain Dew. Most equipment has a weak spot and this is the 401’s. The voltage regulator […]
